Rotating Lasers / Rotary Lasers
All RedBack Rotating Laser models above are electronic self levelling. They come standard with Ni-mh rechargeable battery pack and charger included, so, no burning through one use batteries. All models feature RedBack’s steel internal chassis safety cage and come with an automatic five year warranty, in other words, peace of mind.
Built Tough Steel Chassis
These RedBack lasers are built seriously tough, designed for professional users requiring reliability and accuracy.
Which Model Rotary Laser Tool
Select the rotating laser model you want whether you need grade or vertical rotation, scan lines and green beam for indoor work or upgrade to a millimeter display receiver. The choice is yours.
RedBack Lasers have two core rotating laser tool models. Firstly, the EL614 with Horizontal Operation and secondly, the EGL624 with Horizontal & Vertical Operation. Each of the core models can be purchased as a “GM” or Auto Grade Match Tracking version (EL614GM & EGL624GM/GREEN624GM).
Auto Grade Match Tracking Rotating Lasers
So what is Auto Grade Match Tracking?
This is when you can set the laser unit at a particular height. Then locate the special Auto Grade Match Millimeter Tracking Receiver (LR720T) at a second height along a particular axis. You press a button on the receiver which then communicates to the laser unit. The laser beam then tracks to the receiver’s height and locks on to that grade, making it simple and automatic. Auto Grade Match can be used in two main ways;
First, by setting a grade in the same manner as a manual grade match, but, this time the laser searches for and locks on the receiver automatically. No first finding level and then moving the receiver the required height to match to. For example, when holding the receiver 6m from the laser moving the receiver 100mm from level to get a 1 in 60 grade slope.
The second main method is when you want to match an existing grade or slope on site. An example would be setting a constant grade for a driveway on an undulating hill side. The idea is that you are wanting to match the general existing grade but want to take out all the lumps and bumps along the way.
This is achieved by setting the height of the rotating laser and receiver on the staff at the same height from the ground. Take the receiver up or down the hill along one of the two axis. Then press the Auto Grade Match tracking button and select the axis on the receiver and the laser level does the rest. Tracking to and locking onto the position of the receiver and fixing that grade. When the grade is fixed, you use the receiver anywhere along that axis and a level reading now indicates that you are on that constant grade.
Auto Tracking for Vertical
There is a third use for Auto Grade Match rotary lasers which is supported by the RedBack EGL624GM and GREEN624GM models. That is using it in the vertical plain for automatic alignment for fence lines etc.
Simply set the rotating laser on its side for vertical rotation with the plain of rotation roughly aimed to the other end of the run you wish to align. Set the receiver up on its side at the far end of the run. Again select auto grade match on the receiver (this time it has to be the “X” axis) and the beam automatically tracks left to right to find and lock onto the position of the receiver. You can even perform site squaring as the visible dot laser beam is at 90 degrees to this vertical rotating plain.
